Unformatted text preview: STA 3024 Practice Exam 2 Name: UFID: • On the answer sheet at the back of the exam write your name, UFID, and ONLY the letter corresponding to your answer (do not show your work.) • A formula sheet, F table, and t table are provided on the last page. I promise not to cheat on this exam. I understand that accessing notes programmed into my calculator constitutes cheating. I also promise not to share information about the exam with people who haven’t taken it yet. Signature: 1. In the one-way ANOVA F test, which of the following would lead us to conclude that it’s reasonable that not all the population group means are the same? (A) a large p-value (B) a decision to reject H (C) both (A) and (B) (D) neither (A) nor (B) 2. In the two-way ANOVA F test for interaction, the alternative hypothesis is that there is (A) interaction. (B) no interaction. 3. In the two-way ANOVA F test for interaction, which of the following corresponds to a small p-value? (A) evidence that there is interaction (B) a large value of F AB (C) both (A) and (B) (D) neither (A) nor (B) 4. A two-way ANOVA F test for the main effect of Factor A yields a p-value of 0.0022. Using α = 0 . 05, we (A) reject H , and we conclude that it’s reasonable that the response variable does not depend on Factor A. (B) reject H , and we conclude that the response variable depends on Factor A. (C) fail to reject H , and we conclude that it’s reasonable that the response variable does not depend on Factor A. (D) fail to reject H , and we conclude that the response variable depends on Factor A. 5. A one-way ANOVA F test yields a p-value of 0.193. Using α = 0 . 05, we (A) reject H , and we conclude that some of the group population means differ. (B) reject H , and we conclude that it’s reasonable that all the group population means are the same. (C) fail to reject H , and we conclude that some of the group population means differ. (D) fail to reject H , and we conclude that it’s reasonable that all the group population means are the same. 6. Which of the following data sets would be most immediately suitable for one-way ANOVA? (A) Explanatory Response Subj. Age Hair color 1 22 Black 2 35 Red 3 26 Brown . . . . . . . . . n 23 Blonde (B) Explanatory Response Subj. Eye color Hair color 1 Brown Black 2 Green Red 3 Brown Brown . . . . . . . . . n Blue Blonde (C) Explanatory Response Subj. Age Income 1 22 \$37,000 2 35 \$56,000 3 26 \$7,300 . . . . . . . . . n 23 \$10,000 (D) Explanatory Response Subj.

A one-way ANOVA with five groups yields the following ANOVA table (some items are missing): Source df SS MS Group 1.326 Error 4.905 0.327 Total One of the missing items is the total sum of squares. Calculate it....
